The allelic nature of five dwarfs (d6, d7, d8, d9 and d10), recovered in M2 after ethyl methanesulphonate treatment of a local rice variety Tellakattera, was studied in relation to the Dee-geo-woo-gen (DGWG) dwarfing gene. The behaviour of the different crosses of the dwarfs with DGWG in F1 and the segregation pattern in F2 clearly demonstrate that these induced dwarfs are non-allelic to the DGWG dwarfing gene. In view of the extensive use of this gene in developing most of the high yielding rice varieties, the new dwarfing genes of Tellakattera may be exploited as alternative sources, to avoid genetic vulnerability.
在对当地水稻品种 Tellakattera 进行乙基亚磺酸盐处理后，在 M2 中回收了五个矮秆基因（d6、d7、d8、d9 和 d10），研究了它们与 Dee-geo-woo-gen（DGWG）矮秆基因的等位性。不同矮秆基因与 DGWG 的杂交在 F1 中的表现和 F2 的分离模式清楚地表明，这些诱导的矮秆基因与 DGWG 矮秆基因是非等位的。鉴于该基因在培育大多数高产水稻品种中的广泛应用，Tellakattera 的新矮秆基因可以作为替代来源加以利用，以避免遗传脆弱性。
